Amazing Apex Trigger by Brian Klein, Verified Owner, May 31, 2018
Installed the Apex Polymer AEK with duty/carry kit for the M2.0. Installed in an M&P 5" FDE w/ safety. The factory stock trigger on the M2.0 is pretty darn good but with the Apex kit it really cleans up the uptake... smooths it out a lot. Kit also re...

Product Info for Apex Tactical Specialties Action Enhancement Polymer Trigger & Duty/Carry Kit for S&W M&P M2.0, M&P 45

The Apex Polymer Action Enhancement Trigger directly replaces the S&W factory hinged trigger with a solid body polymer trigger, and a center mounted pivoting safety. The rounded face of the trigger provides a smooth comfortable surface for the shooters finger while firing. The trigger also reduces pre-travel and over-travel from the factory trigger.image

The Apex Duty/Carry Kit is engineered to provide the Smith and Wesson M&P M2.0 (and M&P 45) pistol owner with a smooth, consistent 5.0 to 5.5 lbs. trigger pull with the advantages of shorter over-travel and shortened trigger reset. All of the components work together to provide a pull weight within the acceptable range for a top end, service pistol. The kit itself is designed to be drop-in and should not require further gunsmithing, however, armorer or gunsmith installation is recommended.

Expected Results

Smooths trigger pull

Reduces trigger pre-travel and over-travel by approximately 30%

Reduces reset length

Reduces trigger pull weight by approximately 1 lb. for a pull weight around 5-5.5 lbs for Duty/Carry applications

Center mounted pivoting safety maintains factory safety values

Applicable To What Gun(s)

Works with the Smith & Wesson M&P M2.0 (9mm/.40S&W/.45ACP), M&P M2.0 Compact, and the M&P (v1.0) 45.

Not for use in the M&P 9mm/40S&W models.

Does NOT function in the M&P Shield.

Does NOT function with the Apex Forward Set Sear and Trigger Kits

In the M&P 45 (this does not apply to the M2.0), you may need to make an adjustment to the trigger bar loop for proper function. This kit REQUIRES the use of the larger 1/8 inch sear spring and plunger set up. If your M&P has a 1/16th inch diameter sear plunger and spring, we strongly advise you upgrade to a new style sear housing block before installing this product. All function and reliability testing was done with a 1/8 inch sear plunger and spring, therefore we cannot guarantee proper function without the appropriate size sear plunger and spring.

Included Accessories:

1 ea. Polymer Action Enhancement Trigger

1 ea. Heavy Duty 1/8" Sear Spring

1 ea. Slave pin (assists with installation of trigger return spring)

1 ea. 2-Dot Fully Machined Sear

1 ea. Duty Carry Trigger Return Spring

1 ea. Ultimate Striker Block Kit (Striker Block, Spring and Talon Tactical Tool)
